Hi everyone- This is my first post. I've been dreaming of raising chickens for a few years and now I'm really going to do it! I'm building the coop and I'm ready to order chicks from the local farm supply store. I want to start with six, my dilemma is I like 3 breeds- Araucana, Black Australorp and Buff Brahmas. Is it ok to get 2 of each? Or should I stick to one breed?
